The achievement marks a major milestone for the company, which has progressed from its first EcoVadis assessment to Gold level in just three years. This rating places WISKA among the top 5% of companies assessed by EcoVadis worldwide at the time of rating.

EcoVadis evaluates organisations across four key areas: environment, ethics, labour & human rights, and sustainable procurement, providing an independent benchmark of environmental and social impact across operations and supply chains.

For WISKA, sustainability is embedded within the company’s culture and long-term strategy. The organisation continues to focus on balancing economic performance, environmental responsibility and social impact, supported by strong environmental management practices and continuous improvement across the business.

Tanja Hoppmann, General Manager and Head of Sustainability at WISKA Hoppmann GmbH, said:

“We are incredibly proud that our efforts to make WISKA more sustainable have been recognised with the EcoVadis Gold medal. This achievement means a great deal to us because it reflects the dedication and commitment of colleagues across the entire WISKA team around the world. Sustainability is something we work on every day, and we strongly believe that innovation plays a key role in creating better, more responsible solutions for our industry. This recognition motivates us to keep pushing forward, continuing to innovate and improving the way we operate.”

The EcoVadis Gold rating reinforces WISKA’s commitment to continuous improvement and responsible business practices.

We say goodbye to a beloved mother and grandmother who was not only the heart of the family, but also a formative part of the family business. As a longtime managing director and shareholder of WISKA, she helped shape the company over many years with her values and commitment. She lives on in our memories and stories – as a role model and inspiration.

“For us, sustainability is not an add-on, but an integral part of our corporate strategy,” explains Tanja Hoppmann, Managing Director of WISKA Hoppmann GmbH. “With this report, we want to show how we balance ecological, economic, and social responsibility.” 

WISKAs strategy is based on three key areas of action: 

Responsibility for the environment: Measures to reduce energy consumption and greenhouse gas emissions and to strengthen the circular economy. Responsibility for employees: Promotion of attractive working conditions, health, safety, and further training. Corporate responsibility: Transparent corporate governance and responsible action along the supply chain. 

The company is publishing a sustainability report for the first time in accordance with the Voluntary Sustainability Reporting Standard for SMEs (VSME). Participation is voluntary – but for WISKA, it is a clear commitment to responsible action and transparency. 

In the reporting year, WISKA implemented numerous initiatives, including:

• Bicycle leasing for employees to promote sustainable mobility.
• The development of a guideline for sustainable procurement and other internal guidelines.
• Introduction of bioplastics: The KA-BIO product range consists of renewable raw materials instead of fossil-based ones. 
• Calculation of the product carbon footprint of the first products and development of the first products with significantly lower PCF (cradle-to-gate).

Despite a 10% increase in sales, energy consumption was reduced by 9% and Scope 1 & 2 greenhouse gas emissions by 5%. These results underscore the company's commitment to climate protection and the continuous improvement of existing processes.

A particular milestone was the award of the silver medal by EcoVadis. This places WISKA among the top 8% of all companies assessed worldwide. 

“With the VSME report, we want to make visible what we stand for as a company: responsible action, measurable progress, and a willingness to continuously develop,” emphasizes Elske Kelm, Sustainability Officer at WISKA.  

“We are convinced that sustainability and economic success are not mutually exclusive, but rather mutually dependent,” adds Tanja Hoppmann. “With our first report in accordance with the VSME standard, we are making this claim visible.”

"It is a pleasure for us to see HSV in the 1. Bundesliga and to be able to be part of it. For us, this col-laboration is a strong sign of our connection to the north of Germany and our roots in Hamburg,‘ says Ronald Hoppmann, Managing Director of WISKA Hoppmann GmbH, which he runs together with his sister Tanja Hoppmann in the third generation. ’Many of our employees are loyal HSV fans who are enthusiastic about football and team sports. That's why we not only want to show our presence, but also create experiences: in the stadium, with our customers and for our employees and their families."

A clear commitment to Hamburg and the region
WISKA was founded in Hamburg in 1919 and is now firmly rooted in the north, with its headquarters in Kaltenkirchen. The partnership with HSV is an expression of this regional connection and the val-ues shared by both sides: team spirit, passion and consistency. For WISKA, this commitment is more than just sponsorship: it is an emotional commitment to Ham-burg, to the north of Germany and to the people who live and work here. ‘This partnership underlines our brand value of “ together”. Football is a team sport that brings people together – and that matches with our culture,’ adds Kristina Wilkens, Head of Marketing.

Outlook
As part of the partnership, plans include a presence at home games, events at the Volksparkstadion, competitions and joint content for the HSV and WISKA channels. In addition, WISKA also wants to offer employees and customers special experiences related to HSV – from free tickets to games to visiting the stadium together. As a family-oriented company, it is important to WISKA to involve not only its employees but also their families.

WISKA presents: the future of cable glands - TriShot®!
The TriShot ® is more than a cable gland, it is the result of continued drive to push boundries and possibilities. To be a pioneer and lead the way in 3 core principles: Innovation, Sustainability and Performance.
This cable gland is designed to perform. IP68 protection with or without cable/blind plug, quick installation, large clamping range (6 - 14 mm), built in seal, i.e. no inserts required and any cable type is sealed and with an impressive 54% reduction in product carbon footprint compared to conventional cable glands, the TriShot ® has an excellent sustainability performance.

Same quality, new origin: The WISKA KA series made from BIO-plastics!
The first product range from WISKA made from plastics that are no longer of fossil origin but are manufactured from renewable raw materials, so-called bioplastics. During their growth phase, the raw materials of these plastics absorb CO² and bind it throughout their utilisation phase. When our bioplastic products are used to generate energy at the end of their life cycle, they release only as much CO² as the plants used to make the raw material previously absorbed. The target is a closed CO² cycle that conserves limited resources.

The COMBI® 304 system consists of a rotary switch, a junction box and an LED light - perfect for use as garden lighting, path lighting, carport lighting or industrial design lighting. A perfect blend of functionality and design with the reliability of a system! Each product has four M20 threaded membrane entries and has a diameter of 82 mm.

For technical outdoor lighting, with its 4010 and 2010 LED multi-purpose luminaires, WISKA offers compact and very flexible products with a long LED lifetime and material advantages for sustainable installation. These are complemented by the new LED floodlight 5010, a product complement of the LED floodlight 5000 with High-Lumen-Output, 1x 220W or 2x 200W and separate ballast unit. The new WISKA LED searchlight extends the popular octagonal design series and can be used as a searchlight or floodlight with 2x 18,000 lm and IP 66/68, in endless rotation, with stepless speed and morse function. With its new remote control unit, operation is a child's play.
The WISKA HNA installation material made of brass were the first WISKA products that the company produced when it was founded in 1919. Just a few years later, the first plastic products were added, especially for the non-maritime market. WISKA now finally offers a high-quality, seawater-resistant plastic alternative for the classic maritime brassware - lead-free and even in protection class IP66/67. The COMBI® MARITIM 304 system consists of a junction box, rotary switch and LED light - manufactured from polypropylene and TPE in twin-shot injection moulding in Kaltenkirchen, supplied in black and with WISKA cable glands ESKV (junction box and rotary switch). "With its low weight and long life, our COMBI® MARITIM 304 system offers clear advantages for installation and the environment. All this made in Germany.," says Ronald Hoppmann, General Management. Of course, WISKA will also be showcasing its market-leading VARITAIN® reefer container sockets and cable entries at SMM.

The lighting and installation ranges are rounded off by WISKA CCTV video surveillance: The current CS-S camera series with its 360° pan/tilt unit or as a fixed camera housing offers 512x zoom at 4 megapixel resolutions in operating temperatures between -30°C and +55°C.

All products are developed and produced by the company itself and run through the entire value chain at WISKA.

The WISKA team at SMM: Hall B6, Stand 212, stand party on 04/09/2024 from 5 pm.

Within its constantly growing range of technical lighting products, the company is presenting the new non-metallic LED multi-purpose luminaire 4010 with a luminous flux of 1,200 up to 7,200 lm and a lifetime of 100,000 hours. In addition to the long standard version with 775 mm, there is also a short version with only 495 mm. The high-performance lighting, optionally also with battery back-up, is corrosion-free and easy to install. It is ideally suited for use on car ferries, among others.

With the new LED searchlight, WISKA extends its existing range with a LED version. Its casing adds a complete new development to the familiar WISKA octagonal design. It can be used as a searchlight or floodlight and offers two times 18,000 lm. The new product features endless rotation, stepless speed control, a home and booster function and can be used at minus 25 °C to plus 45 °C. The LED innovations are rounded off by a new high-lumen output version of the floodlight 5000.

The new CCTV camera series also offers a new design: The new camera station can be rotated 360° endlessly thanks to its newly developed pan-tilt unit, while its variant as a fixed camera housing is fixly installed. With a new compact design without external cables and with an internal connection compartment, the new series replaces the entire previous WISKA stainless steel series.

WISKA will also be showing in its new COMBI 304 MAR series a junction box and a rotary switch at SMM. "In the area of installation material, our new COMBI 304 box brings along our many years of experience in non-metallic installation material from various industrial sectors. The two-component injection moulding made of polypropylene and TPE convinces at IP66/67 rating and is manufactured in our factory. Supplemented by its variant as a rotary switch, our 304 has what it takes to deliver a real alternative to the previous HNA products made of brass," says Ronald Hoppmann, WISKA General Manager, adding "We are very pleased to finally be back at SMM and to talk with our guests."

The MagikNUT is a new polyamide EMC locknut with an integrated stainless steel clip. The EMC installation is easy and quick: The approx. 1 cm stripped off shielded cable is contacted by the claws of the stainless steel clip within the locknut. In addition to the considerably simplified shield contacting, the MagikNUT polyamide design also enables a simple EMC solution for plastic cable glands: The user benefits from maximum flexibility, from standard cable glands to threaded membrane entries and conduit fittings for cable protection. The new WISKA locknut is lightweight, available in M16, M20 and M25 and black or grey. All information on wiska.com.

"Security through CCTV video surveillance is part of our daily work, so it was only logical for us to start right here especially with the need for increase safety measures in the wake of the Covid-19 pandemic. With the new camera solution, we are able to meet the protection requirements for guests and employees exceeding the required social distance measures, contact-free but with AI-precise accuracy at +/- 0.3°C," says Ronald Hoppmann, WISKA General Manager.

For indoor applications, a distance of 3 meters is required between the camera and blackbody. The blackbody is the device used to measure and reference the temperature. An individuals forehead temperature is measured with high efficiency and in real time – at different distances depending on the product version. The unit can measure up to 15 people simultaneously; this makes the solution equally suitable for low to high traffic areas. Measurements are reliable even when wearing a mask and result messages can be supported by an integrated alarm management. WISKA only displays, does not store or process the data generated - all legal requirements are met.

"The safety requirements have increased across all areas – that is why we are now thinking of new applications for our products. In particular, video surveillance offers unexpected possibilities, from body temperature measurement to fully automated mask recognition to access control in high traffic areas, there are hardly any limits to development - certainly also for the maritime industry. And best of all: These solutions can be seamlessly integrated into our existing CCTV networks," explains Rico Feldmann, Director Business Unit CCTV at WISKA. With their digital video systems, WISKA offers internationally certified solutions for a wide range of applications, from outdoor to indoor, night vision and explosion protection to searchlight combinations.

With the COMBI 304 junction box, WISKA is not only introducing a new size box within its popular COMBI® series, but also a new design: The COMBI 304 is the first circular COMBI box with a diameter of 82 mm, 57 mm high and, especially in its standard colour black, is also ideally suited for use in architectural and retro design projects. The rotary switch version of the 304 perfectly rounds off the design aspiration of the 304 enclosure. The 304 offers 4 M20 threaded membrane entries, which can be used with the cable directly entered through the membrane (IP66) or via WISKA cable gland (IP67), with their conduit fittings (BraceFITTING) or rigid conduit fittings (KRASM). The flat lid of the new box can be closed as a bayonet cap with only a quarter turn; two external mounting lugs with a distance of 90 mm allow for convenient installation.

In addition to the 304, the new and largest WISKA COMBI box 1610 (200x160x94 mm) also expands the range - and is available as a high-quality junction box with cable diameters up to 16 mm² for electrical installation, automation and industry, e.g. also for CCTV and Wifi interfaces and repeaters. With its high protection class IP66/67 and the high-quality plastic injection moulding, the box is UV and ozone resistant like all of its series and therefore ideally suited for indoor and outdoor use. Cable entry with the 1610 is via up to 30 knockout entries from M20 to M40; options such as a clear cover or closed sides are available. Full information on wiska.com.
